JH21 series high-speed punch press

Detailed introduction:

Performance characteristics of JH21: ·High quality steel plate welded body, all undergo tempering (or vibration aging), shot blasting treatment, good rigidity, and stable accuracy; ·The crankshaft is vertically arranged with a compact structure. After high-frequency quenching and grinding treatment, the crankshaft has good smoothness and flexible rotation; Rectangular six sided extended guide rail, with bronze paneling on the guiding surface, high guiding accuracy; ·Pneumatic dual balance cylinder, balancing the weight of the slider and upper mold, reducing impact and noise, eliminating the gap between the connecting rod and slider, and reducing the impact and wear of stressed parts; ·The overall system adopts imported PLC centralized control, and the air circuit is controlled by imported safety double valves, which can achieve jog, inch, single and continuous stamping; ·The key components such as slider, guide rail, worktable, connecting rod, and sleeve are all made of resin sand. Compared with general clay sand manufacturing, it improves surface roughness by 1-2 levels and increases dimensional accuracy by 2-3 levels; JH21-60 and above tonnage products adopt electric adjustment of mold height; Premium configuration, key components such as pneumatic components, electrical components, seals, buttons, etc. are all imported
